Abstract
In a rotating electric machine, a stator includes a stator winding, a field winding includes a series-connection body including a plurality of winding portions, and a rotor includes main pole portions protruding from a rotor core in a radial direction. A harmonic current for inducing a field current in the field winding flows to the stator winding. A rectifying element is connected in series to the field winding, configures a closed circuit with the field winding, and rectifies the field current that flows to the field winding to flow in one direction. In a capacitor, a first end is connected to a connection point between adjacent winding portions and a second end is connected to either of both ends of the rectifying element. A partitioning portion is disposed between at least a single set of adjacent winding portions among the plurality of winding portions and includes a magnetic material.
